There will be significant changes throughout the SEC in 2016.

Georgia, Missouri and South Carolina have new head coaches who brought in most of their  coaching staff.

National champion Alabama will lose Heisman Trophy winner Derrick Henry and most of its dominant defensive front to the NFL. Ole Miss is expected to lose three first-round draft picks.

But several teams are in need of change, especially at quarterback. Top high school recruits and transfers could improve several teams in the conference.

Here’s a look five SEC teams that should have significantly different looks next season:

ALABAMA

The SEC team that had the most, loses the most. It makes sense. But under Nick Saban, the Tide always has talented players ready to step in. And next season is no exception. On offense, the Tide must replace QB Jacob Coker, Rimington Award-winning C Ryan Kelly and RT Dominick Jackson as well as Henry. The biggest question is quarterback, where the best scenario would be for Blake Barnett, a five-star recruit from California who redshirted this season, to claim the job in the spring. A dual threat, Barnett has the talent to be the Tide’s best quarterback in decades. Speedy Kenyan Drake returns at running back, but Henry’s successor could be sophomore Bo Scarbrough, who carried only 18 times for 104 yards and is widely expected to be the Tide’s next star back. On defense, the competition should be fierce to fill the spots on the line and at linebacker. The secondary should be solid with a battle to replace Cyrus Jones at cornerback.

ARKANSAS

Like Alabama, the Razorbacks lose their quarterback, top running back and best offensive lineman. The most important spring battle will be at quarterback with junior Austin Allen, trying to take over for his brother Brandon, a three-year starter. The main competition is expected from Ricky Town, a transfer from Southern Cal. There also should be a battle to replace Alex Collins at running back. Kody Walker, a 6-foot-2, 247-pound bruiser, could return. Other candidates include sophomore Rawleigh Williams III, who rushed for 254 yards last season, or 6-0, 209-pound incoming freshman Devwah Whaley, a four-star recruit from Beaumont, Texas. The Hogs must also replace C Mitch Smothers and G Sebastian Tretola, who shared the Jacobs Trophy as the SEC’s best blocker with Alabama’s Kelly.

AUBURN

Expect Gus Malzahn to work overtime to make his offense look much different in 2016. His ability to make improvements should depend on his quarterback situation. Jeremy Johnson and Sean White return, but weren’t close to following in the footsteps of Cam Newton or Nick Marshall. Junior-college transfer John Franklin, who started his career at Florida State, will get a look in the spring. He’s the only quarterback the Tigers have signed or gained a commitment from for next season. Though he struggled last season, Johnson has the physical talent and could develop. Four-star recruits Eli Stove and Kyle Davis could be immediate contributors at receiver with the departures of Ricardo Louis and Melvin Ray. On defense, the Tigers trade one premier defensive end for another. Carl Lawson returns from an injury, replacing Cassanova McKinzy.

FLORIDA

Who’s going to play quarterback? Will incoming freshman Feleipe Franks be ready? Those are the major questions for the Gators, who won the SEC East but faded with three successive losses to finish the season. Coach Jim McElwain may need to adjust the Gators’ offense to fit the quarterback. The main candidates include Luke Del Rio, a transfer from Oregon State and Alabama, Franks and holdover Treon Harris, who has been ineffective the past two seasons. Del Rio, son of Oakland Raiders coach Jack Del Rio, has the advantage of working with Gators coaches Doug Nussmeier and John Garrett, who were assistants at Del Rio’s previous two stops. Sophomores Jordan Cronkrite and Jordan Scarlett are candidates to success Kelvin Taylor at running back. But junior-college transfer Mark Thompson, 6-2, 230 pounds, could emerge as the featured back. Freshman Joshua Hammond, another four-star recruit who enrolled early, could provide another playmaker at receiver to join Antonio Callaway.

MISSISSIPPI STATE

What will the Bulldogs do without Dak Prescott, who supplied more than 70 percent of the offense last season, leading the team in rushing as well as passing? Nick Fitzgerald is the likely successor. Coach Dan Mullen, an outstanding quarterback coach, has guided the Bulldogs through smooth quarterback transitions in the past. Mullen gave Fitzgerald some opportunities this past season to try to prepare him. Elijah Staley, another redshirt sophomore, is the other expected candidate. The new quarterback will lose two offensive linemen and deep-threat WR De’Runnya Wilson, who caught 10 TD passes this season. But the receiving corps is deep. The Bulldogs are in the running for A.J. Brown, a four-star receiver from Starkville with big-play potential. The defense loses lineman Chris Jones and CB Will Redmond to the NFL Draft. The Bulldogs need playmakers, and one possibility is redshirt freshman RB Nick Gibson, a four-star recruit.
